Fluke Multifunction Installation Tester

Multifunction Installation Tester is designed for comprehensive electrical installation testing and commissioning applications. It provides fast high-current loop testing, variable RCD current testing, voltage measurements and loop and line resistance measurements.

The tester supports RCD testing for different RCD types, including general, time-delayed, pulsed-signal, AC and Type B RCDs. It provides PASS/FAIL indication for RCD tests and supports customized current settings.

The instrument provides continuity testing, insulation resistance measurement with test voltages from 50 V to 1000 V, loop impedance measurement in high-current and non-trip modes, PFC/PSC testing, earth resistance measurement and phase sequence indication.

Extended memory and documentation functions support recording and reporting of measurement results. A zero adapter is provided for easy test lead compensation.
